Frequently Asked Questions (FAQs)

What are the key specifications to consider when selecting a crane in China?

When selecting a crane in China, several key specifications need to be considered to ensure the crane meets the specific needs of the application and operates safely and efficiently. These include the load capacity specification, which indicates the maximum weight the crane can safely lift, and is crucial for determining the crane’s suitability for the intended tasks. Other important specifications include boom length/reach, which defines the crane’s ability to lift items at greater distances or heights; hoisting speed, which outlines the speed at which the crane’s hoist system can raise or lower loads; operating radius, which specifies the maximum distance at which the crane can operate effectively; and power source, which details the type of power the crane uses, such as electricity, diesel, or hydraulic.

How is the lifting capacity of a crane specified and what factors influence it?

The lifting capacity of a crane is specified as the maximum weight that the crane can safely lift in a single operation under normal working conditions. This capacity is typically measured in tons or kilograms and is influenced by several factors, including the strength of the crane’s components, the length and configuration of its boom, and the stability of its base. For example, the rated lifting capacity does not include the weight of the hook and the moving pulley group, but it does include the weight of detachable material handling devices like grabs and electromagnetic suction cups. Additionally, for variable-radius boom-type cranes, the lifting capacity varies with the working radius.

What safety features are typically included in crane specifications in China?

Crane specifications in China often include a range of safety features to enhance the safety of crane operations and reduce the risk of accidents. These features can include load moment indicators, which alert the operator if the crane is approaching its load limit; anti-collision systems, which prevent the crane from colliding with other cranes or obstacles; emergency stop buttons, which allow for immediate shutdown in emergency situations; and overload protection systems, which prevent the crane from lifting loads that exceed its rated capacity. Additionally, cranes may be equipped with visual inspections such as load rating charts and controls inspections to ensure compliance with standard designs and safety standards.

What are the regulatory requirements for crane inspections and certifications in China?

In China, cranes are subject to stringent regulatory requirements to ensure safety and compliance. Before manufacturing or modifying cranes, manufacturers must submit type inspection applications along with detailed documents, including strength calculation bases, assembly sketches, and the educational background and working experience of key personnel. The inspecting organization issues a Qualification Certificate of Type Inspection for Manufacturing Equipment after passing the inspection. Cranes must also undergo simulated load tests and completion inspections, and any alterations to the crane’s structural parts require additional inspection and certification. Imported cranes may be granted exemptions from certain inspection requirements if they have substantial inspection certificates from their country of origin.

How are crane inspections and maintenance protocols implemented in China?

Crane inspections and maintenance protocols in China are designed to ensure the quality and safety of the equipment. These protocols include materials inspection to verify the quality of materials used, such as metals for hooks and electrical parts; visual inspection to check for load rating charts, controls, and other critical components; and performance inspection to verify the crane’s ability to lift, lower, and hold loads safely. Regular maintenance and inspections are also crucial, with records kept of all maintenance and repairs to detect any recurring issues. Inspectors must be highly qualified, and inspections must follow updated international standards and practices to maintain integrity and accuracy.
